He said it would be a sad day for the country if there was no truth to the allegation because dirty politics had been used to tarnish a transparent administration.

Parti Keadilan Rakyat (PKR) advisor Datuk Seri Anwar Ibrahim had denied that he was the man in the sex video, revealed by an unidentified group led by one Datuk T, and that he was with his family at home and tweeting as well as surfing his Facebook account on Feb 21, the date that the video was said to have been recorded.

The group had alleged that it had a black-and-white video clip of a sexual act between an opposition leader and a woman said to be a prostitute at a hotel.

"In my opinion, dirty politics is an embarrassment. Give us enough space to do our job because it is for the good of all.

"While politicians must be clean in character, we also must give space to people and we cannot just all the time follow (them) even to the toilet.

"There is the personal life and there is the political life," he told a news conference after attending a tea reception in appreciation of Selangor Technical Department officers, organised by SSIC Bhd here.

Meanwhile, Abdul Khalid praised the SSIC for raising its targeted RM10 billion in investment for Selangor last year, saying that the development reflected maturity in investment last year compared to 009 and 2008.
